Another example of the usefulness of web scraping is to retrieve data2 from a site. For example, taking data from various marketplace sites to compare the price, showing the schedule of Imsak in which the data comes from KEMENAG, take the weather forecast data, and many others. Web scraping can also be used to export a collection of data list from website to CSV file format, JSON, Excel, etc.

Actually, you don't need to worry about all that. For being the first publish content, Google will index your posting you like the original and the rest will be regarded as a copy or duplicate content.
Our content may often copied-paste and they try to profit from our content, but it's impossible to stop it. Even though we have the force of law for content, but need a great effort to overcome it.
Although some bloggers and writers have asked readers to not copy or at least give the attributes returned in the main site. But in fact, most web scrapers don't really care about this request.
